Previously working Xbian setup no longer working...

[petebulley]

I have been using Xbian for a while now and my setup was working flawlessly - I just moved house and so everything was unplugged and moved and then setup again, however, now I'm having boot issues.

Everything is the same in terms of setup apart from the geographic location!

Software
XBian version: Xbian stable RPi2
XBMC/Kodi version: -
Overclock settings: -

Hardware
Device type and model: Raspberry Pi 2 Model B
Power supply rating:
SD card size and make/type: 16GB Sandisk Ultra
Network (Ethernet or wireless): Ethernet
Connected devices (TV, USB, network storage, ...): USB Harddrive

Problem description:

• On plugging in power cable power light is on, but green light flashes twice
• Have tried using a different SD card with a fresh format and Xbian image
• Have tried using the same SD card that was previously working but formatted and with fresh image
  

How to reproduce:

• Plug in power cable
• Green light flashes twice
• As per http://elinux.org/R-Pi_Troubleshooting 2 flashes means SD card cannot be read - however it could be read last week and for many months, and new card / formatting does not solve
  

Could this be an issue with my Pi?
Any suggestions very much appreciated.

Thanks
